”There is nothing more difficult to carry out, nor more doubtful of success, nor more dangerous to handle than to initiate a new order of things. For the reformer has enemies in all who profit by the old order, and only luke-warm defenders in all thosewho would profit by the new order. This quality of lukewarmness arises partly from a fear of adversaries, who have the law on their side, and partly from the incredulity of mankind, who do not truly believe in anything new until they have had actual experience of it.”
